Parmelia Schaereri
''Placocarpus schaereri'' is a species of saxicolous (rock-dwelling), areolate, and crustose lichen in the family Verrucariaceae. Found in Europe and West Asia, it is the type species of genus '' Placocarpus''. Juvenile forms of ''Placocarpus schaereri'' are often parasitic on the lichen '' Protoparmeliopsis muralis''. Taxonomy The lichen was first described scientifically in 1831 by Elias Magnus Fries, who called it ''Parmelia schaereri''. The species epithet honours Swiss pastor and lichenologist Ludwig Schaerer. Othmar Breuss transferred it to the newly reinstated genus '' Placocarpus'' in 1985. This species has been known by several synonyms throughout its taxonomic history, including ''Placocarpus saxorum'', ''Endocarpon saxorum'', ''Endocarpon miniatum'' var. ''monstrosum'', ''Placidium monstrosum'', ''Verrucaria monstrosa'', ''Dermatocarpon monstrosum'', ''Verrucaria schaereri'', and ''Catapyrenium schaereri''.

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. He is sometimes called the Mycology, "Linnaeus of Mycology". In his works he described and assigned botanical names to hundreds of fungus and lichen species, many of which remain authoritative today. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he studied under Carl Adolph Agardh and Anders Jahan Retzius. He obtained his doctorate in 1814. In the same year he was appointed an associate professorship in botany. Fries edited several exsiccata series, the first starting in 1818 under the title ''Lichenes Sveciae exsiccati, curante Elia Fries'' and the last together with Franz Joseph Lagger under the title ''Hieracia europaea exsiccata''. He was elected a member of the Royal Swedish Academ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Candelariella Medians
''Candelariella'' is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genus was circumscribed in 1894 by Swiss lichenologist Johannes Müller Argoviensis, with '' Candelariella vitellina'' assigned as the type species. Characteristics The key feature of ''Candelariella'' species are the distinct yellow apothecia. Although all species are very small, even the smallest can be identified by the lemon-yellow to orange-yellow discs. Most species have a yellow thallus, although '' Candelariella antennaria'' is one example with a grey thallus. Some species are pycnidiate. This genus will generally have all spot tests emerge as negative, although K tests may have an orange or reddish colour on some species' apothecia. Spore count between species varies from 8 to 32 simply or thinly septate spores. Spores often hold one to two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Črni Kal
Črni Kal (; ) is a village in southwestern Slovenia in the City Municipality of Koper. It is best known today for the Črni Kal Viaduct, the longest and the highest viaduct in Slovenia. Name The name ''Črni Kal'' literally means 'black pond', based on the common noun ''kal'' 'pond, watering hole' and referring to a local geographical feature. Architecture Houses The village has some good examples of traditional Karst architecture. One such monument is the Benko House, built in 1489 by stonemasons Andrej (Andrew) and Benko (Benjamin) as indicated by an inscription on the building: ''Andreas et Benco construxerunt''. This makes it oldest surviving farmhouse in the Koper area and is also the oldest signed and dated secular building in all of Slovenia. It stands on the lower edge of the village core and is made of chiseled limestone and marlstone blocks. It comprises two buildings with inscriptions in the Glagolitic alphabet on the facade.

Alps
The Alps () are some of the highest and most extensive mountain ranges in Europe, stretching approximately across eight Alpine countries (from west to east): Monaco, France, Switzerland, Italy, Liechtenstein, Germany, Austria and Slovenia. The Alpine arch extends from Nice on the western Mediterranean Sea, Mediterranean to Trieste on the Adriatic Sea, Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrust fault, thrusting and Fold (geology), folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 82 peaks higher than List of Alpine four-thousanders, . The altitude and size of the range affect the climate in Europe; in the mountain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolomite Rock
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 million years in age). One of the first geologists to distinguish dolomite from limestone was Déodat Gratet de Dolomieu, a French mineralogist and geologist after whom it is named. He recognized and described the distinct characteristics of dolomite in the late 18th century, differentiating it from limestone. Most dolomite was formed as a magnesium replacement of limestone or of lime mud before lithification. The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Calcareous
Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime (mineral), lime or being chalky. The term is used in a wide variety of Science, scientific disciplines. In zoology ''Calcareous'' is used as an adjectival term applied to anatomical structures which are made primarily of calcium carbonate, in animals such as gastropods, i.e., snails, specifically in relation to such structures as the operculum (gastropod), operculum, the clausilium, and the love dart. The term also applies to the calcium carbonate Test (biology), tests of, often, more-or-less microscopic Foraminifera. Not all tests are calcareous; diatoms and radiolaria have siliceous tests. The molluscs are calcareous organisms, as are the Calcarea, calcareous sponges (Calcarea), that have spicules which are made of calcium carbonate. Additionally, reef-building corals, or Scleractinia, are calcareous organisms that form their rigid skeletal structure th ...

Catapyrenium
''Catapyrenium'' is a genus of squamulose lichens in the family Verrucariaceae. These small lichens grow as clusters of tiny scales ( that lie flat against rocks and soil, often in dry or disturbed habitats. The genus includes about 18 species found worldwide, particularly in arid and semi-arid regions where they help stabilize soil surfaces. Taxonomy The genus was circumscribed by the German botanist Julius von Flotow in 1850. He assigned '' Catapyrenium cinereum'' as the type species. Description ''Catapyrenium'' species form a low, scale-like lichen body (thallus) composed of numerous minute lobes () that hug the rock or soil surface. Each squamule is anchored by a felt of fine, root-like fungal threads (rhizoidal hyphae) that may be colourless or tinged brown. The upper skin () is thin—about 10–30 micrometres (μm)—and uneven, merging almost imperceptibly with the underlying green-. This cortex is built from tiny, angular fungal cells only 5–8 μm across.
